TQ all whom 'it may concern.'

Be 1t known 'that I, GEORGE CLAUSING, a

i citizen of the United States,l residing in the' city of Portsmouth, in'the-"county of Scioto and State of Ohio, bave-invented certain new anduseful Improvements in Lasts, (Case H,) of whiehthe following is aspecific-ation.

The object of the invention is to produce a simple, strong, practical"and rigid last which can be readily broken or fiexed so as to faciiitatethe' removal of the last'rom the shoe and so that the Ashoe will not bemarred, broken or ulledout of shape during the` removal of t e last fromthe shoe.

.l According. tothe presentv invention a last is constructed Aso that itwill comprise a forward or toe part and a rear or heel vpart which areprovided between them with main hearing pins or members that extendtransversely to the last.v The heel and toe parts Y are connectedtogether by a longitudinally extending rod or link, one end` of whichrod is' pivotally conneetedto the toe part and the other end of which ispivotally connected to the heel part. When this link occupies its lowerposition the heel and toe parts voccupy their unbroken position relativeto'eacb other. This link is normally presseddownwardly by a compressionspringr which is located in the toe. part above said li'nk.

As showimgr a specific embodiment ot the invention reference is made tothe drawing forming a part of this specification and in which,-

Figure 1 is a vertically and longitudinally extending sectional view ofthe last. In this figure the full lines indicate the position of theparts when in extended or unbroken position, While the broken linesindicate the position of the heel part relative to the toe pair't l,whenthe last is broken or fiexed. Fig.

Fig. 3is a transverse sectional view taken on the line 3--3 of Fig. l lookingIin the direction of the arrows. Fig. 4 is a seetional view ot' the toepart showing` the manner in which 'the iink rei-airing' opening may beformed. l

The last A comprises the forward or toe part B and the rear or heel partC. In the construction of the ias't the toe and heel SpecificationofLetters Patent. i Patented Aug'. 18, 1914;, Application filed February12, 1914. Serial No. 818,353.

by transversely sawing as along t-he ine dd and a V shaped portion d, eand f is sawed out and removed from the last whereby the heel part canmove from the position indicated by the full lines in Fig. 1 to theposition indicated by the dotted lines in order to break, flex orshorten the last. vAt the juncture of the saw cuts indicated by the liner-d on one hand and by the line e-f on the other, there is located themain bearing members or pivot pins F-F. .These pins are preferablyseeiired as by the pins or nails f-f to the toe part of the last. Itwill be manifest however that in s ome constructions these main bearingmembers instead of beingr independent from may he formed integral withand of the same material as the toe art, for instance, since all that isnecessary 1n the last construction is to have circular hearing surfaceonone of the partsA which can fit into the curved recess portions on theother part- Afterthe heel and toe parts have been separated bytransversely sawing 'along the4 li ne (I-d, they are each provided withopenj ings for receiving the connecting link or bar (i. These openingsmay be formed by boring in each part a couple of openings q(/'-g,inclined to each other. 'Thesebored openings run into eaoli other andthe materialgns g, between the-m is subsequently removed, thus forn'ngthe triangular shaped opening h in the toe part and the opening in theheel part. This connecting link, which is shown of circular crosssection, is pivotally connected to the Vtoe part by the pin orrivet 7'and to the heel part h v pin or rivet lc. .One of the openings throughwhich one of the pins or rivets pass is elongated, as at 7),to permitthe. heel and toe parts to be moved to full fiexed position whendesired. This linkis arrangedA swings to the cdotted position shown inFig.v

i so that the line passing through said pivot centers is located abovethe axis of the main hearing pins F when the heel part occupes theposition indicated by the broken lines, or namely, when'the heel and toeparts occupy the fullv vflexed or broke-n position. The. toe part isalso provided with the ven. ticnlly extending'hored opening Zin whichthere is located the spring means M thatr comprises the con pressionspring' m, and the springr cap n that engnges'thel connectf ing link Gat or adjacent to the central por-v tion of the link. Thisspring, aswill he JJ observed from the drawing, is located above the. connectinglink and normally presses` ngrslinstthe lutter, thus tending to forcethe mst parts -townrdunbroken.position and also tending to nmmtam saidlast partsin 15 said unbroken position .when they are in said position.The linli G serves to connect :1nd hold the toe undl heel ports togetherund asthe control portion-of this link is engaged hy the spring means M,the latter 20 tend to very effectively force the link downwardly andthus securely maintz'iin the heel und toe pin-ts in unbroken positionund in tirni engagement with enr-h other.

From the inspection of Fig. 1' it will'lie full length ofthe forwardtrnnsverselfextendlng face of thc heel pan-t and that-,the mam nearingpins F are shown as being secured tofthc toe pint.'
